PAIENIH; AUG 4 ms 3.751.848 SHEEI 3 0F 3 MODEL nouss BACKGROUND OF THE INVENTION- This invention relates to a model house structure which is useful as a means for displaying or planning interior designs or as a childs doll house.

Heretofore doll houses of various types have been deviced to simulate actual home interiors and thereby provide a recreational and educational structure for children. For the most part such houses were generally permanent structures constructed in -a conventional manner with numerous parts and fasteners. Once constructed or assembled these houses were not adaptable to be easily disassembled for storage or movement to another locality.

It is therefore one object of the present invention to provide a doll house that is comprised of relatively few parts which can be knocked down for shipment and storage and yet can be easily created for use without the need for skilled labor, special tools or fasteners.

Another object of the present invention is to provide a doll house that is realistic and eye-pleasing in appearance.

Yet another object of my invention is to provide a model house that is sturdy, durable and can withstand rigorous use.

Another object of the present invention is to provide a doll house having internal first and second floor areas that are easily accessible from three or more sides of the structure.

Another object of the present invention is to provide a doll house that is well adapted for general ease and economy of manufacture.

Other objects, advantages and features of my invention will become apparent from the following detailed description of one preferred embodiment presented with the accompanying drawings.

BRIEF SUMMARY OF THE INVENTION In general, my model or doll house comprises a plu rality of basic components that-form the floors, the roof and side supporting members that may simulate sidewalls but which leave substantial openings to provide considerable access to the interior floor areas from at least three sides of the house. A first floor or horizontal base member has a series of centrally located slots which receive the lower ends of a vertical transverse divider support member. At opposite ends of the base member are holes or slots for receiving the lower ends of narrow, upright support members that may simulate chimneys.

Along the rear edge of the base member is another slot for receiving a rear upright member that may be long enough to simulate a wall and which is connected to the transverse divider member. Yet another narrow, upright member may be secured in openings along or near to the front edge of the base member to receive and retain a front upright member. The transverse divider member together with the front, rear and end support members hold in place a second floor member and a roof member, all of which are locked together when the house is assembled.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT Referring to the drawing, FIG. I shows a model house 10 embodying the principles of the present invention as it appears when fully assembled for use as a display or recreational device. Generally, it comprises a base or first floor member 12 having a rectangular shape with a similarly shaped second floor member 14 spaced vertically above it. A hinged two-piece roof member 16 is spaced above the second floor member. Holding the floor and roof members firmly together are a pair of end members 18, a front member 20 and a rear wall member 22, all of which are joined to or engaged with edge portions or near-edge portions of both floor members and the roof member. Centrally located within the house is a transverse, upright divider member 24 which provides support to the floor and roof members and also serves to divide the interior floor into room areas. Perpendicular to this divider are a pair of additional divider members 26. A stairway 28 located adjacent the divider members 26 provides a central access between the first and second floors. Since the end members and the front members can be made relatively narrow in width the interior of the house on both floors is readily accessible. This is an important feature because it greatly enhances the use and enjoyment of the house by children as a doll house.

All of the components of my house 10 are preferably made from a suitable sheet material such as wood or plastic board that is relatively light yet durable and similar in appearance to materials used on actual houses. A fairly thick (e.g., one-half inch) plywood such as birch is particularly adaptable because it can be sanded and finished to have smooth, precisely dimensioned surfaces. Another important feature of my invention is that all components of my house can be made from the aforesaid sheet material so that when disassembled they can all be stacked and packaged together in a relatively compact space for storage or shipment.

Turning to FIGS 2 6, the house 10 is shown in greater detail to illustrate the detailed shape and function of various components. The base member 12 has a pair of spaced apart recesses 30 centrally located near its front edge. Similarly spaced apart recesses 32 and 34 are provided at the bpposite ends of the base member. Extending parallel to the rear edge of the base member and alongits entire length is an elongated groove 36. Perpendicular to this latter groove is a T- shaped groove 38 having an inner portion that is parallel to the rear edge groove 36 and'located substantially midway between the front and rear edges of the base member. Near one end of this inner groove portion 40 and spaced from it is a relatively short recess 42. All of the aforesaid grooves and recesses may be routed to a suitable depth within the base member by conventional wood masking tools and it is preferred that none of them extend completely through the base member so that its under surface will remain smooth and unbroken.

The second floor member 14 which has the same rectangular shape as the base member 12 also has cutout portions generally above its various grooves and recesses. Along the front edge of the base member are a pair of notches 44 between which is formed a tongue member 46. At its opposite ends are a pair of elongated rectangular holes or slots 48. The rear corners are each provided with a notch 50 between which are formed a pair of elongated tongue members 52. Extending inwardly from the rear edge of the floor member 14 between its tongue members 52 is a slot 54 which is vertically aligned with the slot 38 when the house is assembled. Spaced from the end of this slot 54 is an opening 56 having slot portions 58 at opposite ends and along one side thereof. These slot portions are vertically aligned with the groove 40 on the base member when the house is assembled. Separating the slot portions 58 is a short tongue member 60.

At the front of the house the front member 20 has a bifurcated low portion with two spaced apart vertical portions 62 forming an opening 64 that readily simulates a front door. Spaced above this opening on the inside of the front member 20 is a horizontal groove 66 having substantially the same width as the tongue 46. The width of material designated by the numeral 68 at the opposite ends of the groove 66 is the same or slightly less than the width of the slots 44. Spaced above the groove 66 is a vertical slot 70 which cooperates with the upright divider member 24 when the house is erected.

At the opposite ends of the house the end members 18 may be relatively narrow, as shown, so as to simulate fireplaces but also to provide easy access to the interiors of both floors. The low end of each member 18 is bifurcated with narrow spaced apart portions 72 forming an opening 74. Above the portions 72 each member 18 tapers to a narrower width which extends upwardly to the second floor level. Here, end member 18 tapers abruptly to a still narrower width by means of a pair of horizontal shoulders 76 on its opposite sides. The narrowest portion 78 above these shoulders has a width only slightly smaller than the length of the slots 48. Near the upper end of this narrow portion are a pair of spaced apart holes 80.

The rear wall member 22 is generally rectangular and has a series of openings 82 which simulate windows. Its thickness is only slightly less than the width of the groove 36 in the base member. Spaced approximately midway between its upper and lower edges is a horizontal groove 84, the opposite ends of which terminate a short distance from the vertical end edges of the wall member. This groove is just slightly, larger in width than the tongue portions 52 of the floor member 14 so as to receive them with a snug fit. Located approximately midway between the ends of the wall member 22 are a pair of vertically aligned and spaced apart slots 86 adapted to receive and retain the divider member 24. This rear wall member, as shown, extends the entire length of the base member and thereby simulates a full outside wall of the house. However, it is apparent that it could be shorter, if desired, particularly if more access to the interior of the house was required from its rear side.

The transverse divider member 24 extends between the rear wall 22 and the front member 20 and helps to hold the second floor in place as well to support the roof l6. Along a rear vertical edge of this divider are a pair of projecting tongue members 88 which are spaced apart and sized so as to fit within the slots 86. Each of these members 88 is generally hook shaped with an upper end portion 90 that extends outwardly and upwardly from the vertical edge of the divider. When these tongue members are inserted into the slots 86, as shown in FIG. 4, their end portions 90 extend above the upper ends of the slots and hold the two adjoining members 24 and 26 firmly together. On the opposite vertical edge of the divider 24 is a similar projecting tongue member 92 also with a hook-like upper portion 94. This tongue member fits into the vertical slot 70 of the front upright member 20 in the same manner as the other tongue members 88. The divider 24 is shaped so that it has an internal vertical edge 96 on one side of cutout portion 97 above the stairwell opening 56 and an internal horizontal slot 98 that extends inwardly therefrom towards its rear edge. The length of this latter slot is such that when the divider 24 is attached to the floor member 14 so that its internal edge 96 is flush with the projection 60, the portion of the divider 24 adjacent its slot 98 will fit in the slot 54 of the floor member. At the top of the divider are a pair of tongue members 99 that are sloped at an angle in opposite directions and are adapted to fit within grooves 101 of the same length in the underside of the roof members 16 as shown in FIG. 3.

The other vertical dividers 26 fit into the slots 58 and adjacent to these divers the opening 56 provides space for accommodating the stairway 28. The stairway is comprised of an inclined member with projecting tongue members 102 and 104 at its upper and lower ends. The upper tongue member fits into a recess 106 provided in the underside of the floor member 14 and the lower tongue member fits into the similar recess 42. A series of horizontal slots 108 are provided in one side of the inclined member 100 for receiving a series of steps 110 each having a similar slot 112.

The roof 16 is comprised of two generally rectangular members that are pivotable around a hinge axis that extends parallel to the rear wall member 22. As shown in FIG. 6, both roof members at both ends of the hinge axis are notched out to receive the upper ends of the upright end members 18. At this point each end member is secured to the roof by a short retainer block 114 which extends across the width of the end member and has a pair of spaced apart dowel pins 116 that project from one side of the block. The dowel pin of each block extends through the openings 80 in the end member and into similar openings provided in the roof members. Thus, the dowel pins serve as hinge means by allowing each roof member to pivot about the aligned pins at its opposite ends. When installed in the block the dowel pins are angled outwardly with respect to each other a small amount (e.g., 1 to 2 and this assures that once placed in their proper position they will essentially grip the sides of their openings and stay in place.

The assembly of my house 10 can be accomplished quickly and easily by an unskilled person, and in fact part of the unique recreational value of the house to small children lies in the process of assembling and disassembling the various components. With the base member 12 supported on a flat surface the center divider 24 is first attached to the rear wall 22 by inserting the rear tongue members 88 into the slots 86. Now, with the back wall preferably resting on a flat surface, the floor member 14 is inserted into the slot 98 of the divider 24 so that its slot 54 receives the divider portion adjacent thereto and until the tongue members 52 of the floor are seated in the groove 84 of the rear wall. The slot 98 of the divider 24 and the groove 84 of the rear wall will be in the same plane to allow connection of these components only when the divider tongues 88 are uppermost in the slots 86. Therefore when the floor member 14 is inserted in the divider 14 and into the back member, the back member becomes locked to the divider. Now, the front upright member is secured in place by inserting the front tongue member 92 on the divider 24, into the slot 70, while the tongue member 46 of the floor 14 fits within the recess or groove 66. This action locks the front member to the divider and in fact locks these members to the floor member 14 in the same manner that it was previously locked to the rear wall member. This connection is made possible by rounding or beveling the top outer edge 120 of the slot 70 and the bottom edge 122 of the floor tongue portion 46. As the front member is connected the rounded edge 120 engages upper portion 94 of the tongue 92 and cams the front member downwardly until the tongue 92 is uppermost in the slot 70 and the tongue portion 46 of the floor member is with the mating slot 66. The end members 18 can now be installed in a similar manner by being inserted upwardly through the floor slots 48. At this point, the assembled components are pivoted into place on the base member with the rear wall situated in the groove 36, the front door member in the recesses and the end chimney members in their recesses 34. Now, the steps 110 can be inserted into the notches 108 of the member 100 to form the stairway 28 and its bottom tongue 104 can be placed in the recess 42 of the base member. By lifting the floor member 14 slightly, the upper tongue member 102 of the stairway can be inserted into the recess 106.

Theroom dividers 26 can now be inserted into the slots 58 adjacent the opening 56 that forms the stairwell.

Now, the roof 16 is attached to the center divider 24 so that the tongue members 99 thereof are inserted into the grooves 101 of the roof. In this position the upper ends of the chimney like end members 18 are situated within the notched out portions at the opposite ends of the roof members. The retaining blocks 114 can now be attached with their dowel pins 116 inserted through the holes 80 and into the roof.

The disassembly of the house is accomplished by merely reversing the assembly procedure and should be readily apparent. When assembled the house is sturdy and stable with the components locked together as described. Yet no fasteners such as screws or bolts are required. The high degree of accessibility of the floor areas greatly enhances the use and enjoyment of the house by more than one child at a time. In the knocked down condition all parts are flat for easy storage and handling.

To those skilled in the art to which this invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without departing from the spirit and scope of the invention. The disclosures and the description herein are purely illustrative and are not intended to be in any sense limiting.
